# ThoughtSync

Self-hosted personal thought-capture web app in the **FabledSword** family — a
Google-Keep-style **masonry post-it board** for capturing disparate thoughts in
under a second, designed to grow into a lightweight second brain (labels, search,
`[[wiki-links]]`, graph).

- **Stack:** Quart (async Python) + Vue 3 + PostgreSQL, Docker, Fabled-Git CI.
- **Auth:** native email + password (signed-cookie sessions). Multi-user with the
  family owner + direct-share + group-share ACL.
- **Web-first.** An Android companion is a later, conditional milestone.

## Layout

```
src/thoughtsync/     Quart app (app factory, auth, models, ACL, config, db)
alembic/             async migrations (schema built via `alembic upgrade head`)
tests/               DB-free unit tests (pytest)
frontend/            Vue 3 + Vite + TypeScript + Tailwind SPA
Dockerfile           2-stage build (Vue -> python:3.12-slim runtime)
docker-compose.yml   local app + Postgres stack
```

## Development

Backend (needs a Postgres reachable at `THOUGHTSYNC_DATABASE_URL`):

```sh
pip install -e ".[dev]"
alembic upgrade head
hypercorn 'thoughtsync.app:create_app()' --bind 0.0.0.0:5000
```

Frontend (proxies `/api` to `:5000`):

```sh
cd frontend
npm install
npm run dev        # http://localhost:5173
```

Or run it in Docker. **Hot-reload dev stack** (edit code, changes reload live) —
Postgres + backend + Vite dev server, app at http://localhost:5173:

```sh
docker compose -f docker-compose.dev.yml up
```

Or the **full production image** (SPA baked in) at http://localhost:5000:

```sh
docker compose up --build
```

## Deploy (self-host)

A complete two-container stack (app + Postgres) you can copy and run. Save it as
`docker-compose.yml`, change the two `CHANGE_ME` passwords (they must match), then
`docker compose up -d`:

```yaml
services:
  db:
    image: postgres:16-alpine
    restart: unless-stopped
    environment:
      POSTGRES_USER: thoughtsync
      POSTGRES_PASSWORD: CHANGE_ME          # change this
      POSTGRES_DB: thoughtsync
    volumes:
      - thoughtsync-db:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U thoughtsync"]
      interval: 5s
      timeout: 5s
      retries: 10

  app:
    image: git.fabledsword.com/bvandeusen/thoughtsync:latest   # :dev for the current dev build
    restart: unless-stopped
    depends_on:
      db:
        condition: service_healthy
    environment:
      THOUGHTSYNC_DATABASE_URL: postgresql+asyncpg://thoughtsync:CHANGE_ME@db:5432/thoughtsync
    volumes:
      - thoughtsync-data:/var/thoughtsync   # uploaded images; omit if you don't use attachments
    ports:
      - "5000:5000"

volumes:
  thoughtsync-db:
  thoughtsync-data:
```

Then open `http://<host>:5000` and register — **the first account becomes the admin**.

- **Only `THOUGHTSYNC_DATABASE_URL` is required.** `THOUGHTSYNC_SECRET_KEY` is optional; if
  unset, a signing key is generated and persisted in the database (sessions survive restarts).
- Uploaded images live under the `thoughtsync-data` volume at `/var/thoughtsync`.
- The app waits for the database and runs migrations (`alembic upgrade head`) automatically on start.
- **Image tags:** `:latest` (stable, built from `main`) · `:dev` (latest `dev`
  build) · `:<git-sha>` on `main` only (immutable, the rollback unit). There are
  no version-shaped tags: nothing pins one, and the build reports its own version
  at `/api/config` and `/health`.
- **Putting it on the public internet:** there are four things to do first — close
  registration, terminate TLS and forward `X-Forwarded-Proto`, stop publishing the app
  port, and back up the attachment volume as well as the database. See
  [docs/public-hosting.md](docs/public-hosting.md), which also lists what the app
  hardens on its own and what it deliberately doesn't.
- **Install as an app (PWA):** ThoughtSync is installable ("Add to Home Screen" / the
  browser's install button) for an app-like window. Browsers only offer install over a
  **secure context**, so put the app behind a reverse proxy terminating **HTTPS** (or reach
  it via `localhost`) — plain `http://<host>:5000` won't show the install prompt.

## Milestones

- **M0 — Foundation & Identity** ✅: Quart+Vue+Postgres skeleton, native auth,
  sharing-ACL spine, Fabled-Git CI.
- **M1 — Capture Core** ✅: note model + masonry board (quick-add, colors, pin,
  edit-in-place, archive, trash+restore).
- **M1.5 — Roles & DB-backed Settings** ✅: first user is admin, admin Settings UI,
  `DATABASE_URL` is the only required env.
- M2 — Organize: labels/tags, search, checklists, attachments.
- M3 — Second-brain seeds: `[[wiki-links]]`, backlinks, graph view, reminders.
- M4 — Launch hardening: responsive/PWA, settings UI, polish.

Work happens on `dev`; `main` is protected (PR-only).
